This looks like the daddy of all regulators.
I thought so...btw that's
mac daddy..
My understanding is that Atomic basically have one design, and substitute higher quality materials for the pricier products - that correct?
Pretty much. As you go up the price range they get lighter also. And the percentage of exotic materials changes. The biggest change is that everything on the T2 is Titanium vs. the others which will use a percentage of Brass or other metal internally. If you read the fine print, you'll notice that the lower end models only get a TI demand lever assy. in the 2nd stages.
One thing about the T2 is that the internal components of the 1st stage are all titanium also so there's never any corrosion should water accidentally get in.
It's slightly lighter than the B2's which might be worth something if you travel a lot like I do - since I carry-on my regs that almost 1lb. difference is nice. I also have the very minimal Scubapro mini-gauges for the same reason.
Anyone here diving with one, if so, what's it like?
It's the sweetest breathing reg I've ever owned. I've occasionally almost forgotten it's in my mouth there's no WOB (work-of-breathing) even at depth. And it stays completely dry, I've been inverted at 120' with no hint of moisture. The best thing about the better Atomics - I think the B2, ST1, and (maybe) M1 all get the TI 2nd stage. It makes a difference in jaw fatigue since it's super light. I dove a B1 before I bought the T2 so I've used Atomic Regs for about 6 years now.
(And how can I get hold of one without giving my bank manager an AGE..)
I don't think you can, they're $1500 everywhere.
Authorized dealers have to pretty much sell at their price. Someone once told me he can get 10% off locally. LeisurePro recently e-mailed that they're selling the M1 discounted.
Consider the new ST1 also, both have the same second with SS used for the 1st stage. It's as corrosion resistant at the T2. Same performance - same 2 year service interval etc. Had they sold it when I bought my T2, I'd have bought it instead and saved $600...
